Hello List,
in the following environment SUSE Linux Enterprise 11SP3 with bind
9.9.4P2 and the Sernet samba packages in version 4.1.7. samba works as
AD PDC. Every few days our bind dns server denies updates. It looks like
a problem with kerberos and the bind_dlz driver:

In this state bind refuses everything.
After restarting bind everything works normal.
Any idea to prevent this?
